Break-Even Calculator

The break-even point is when your total revenue equals your total costs—you're neither making nor losing money. Beyond this point, every additional sale generates profit. It's one of the most fundamental concepts in business planning, helping you understand the minimum sales volume needed to cover all fixed and variable costs.

Break-Even Point (units) = Fixed Costs ÷ (Selling Price Per Unit − Variable Cost Per Unit). The denominator is called the contribution margin per unit. For example, if your fixed costs are $10,000/month, your price is $50, and your variable cost is $30, your break-even is 10,000 ÷ (50 − 30) = 500 units per month.

Fixed costs remain the same regardless of sales volume—rent, salaries, insurance, software subscriptions. Variable costs change with each unit sold—materials, shipping, payment processing fees, sales commissions. Understanding the split is essential for accurate break-even analysis, since only variable costs change as volume increases.

Contribution margin is the amount each sale contributes toward covering fixed costs and generating profit. It's calculated as: Selling Price − Variable Cost Per Unit. A $100 product with $40 in variable costs has a $60 contribution margin (or 60%). Higher contribution margins mean you need fewer sales to break even.

It varies widely by industry and business model. SaaS companies often aim to break even within 18–36 months. E-commerce businesses may break even faster due to lower fixed costs. Hardware startups can take years. The key is having a clear path to break-even and enough funding (runway) to get there. Investors want to see that you understand when and how you'll reach profitability.

Pricing has a direct and powerful impact on break-even. A small price increase significantly reduces the number of units needed. If your contribution margin doubles, your break-even volume halves. This is why pricing strategy is so important—even a 10–20% price increase can dramatically accelerate your path to profitability if demand remains stable.

Break-even analysis helps with: setting pricing strategy, evaluating whether a new product or feature is viable, determining minimum sales targets, making decisions about fixed cost investments (hiring, office space), preparing financial projections for investors, and understanding the impact of cost changes on profitability.

Yes, but you'll adapt the formula. For SaaS, think in terms of monthly recurring revenue: Break-Even = Monthly Fixed Costs ÷ (ARPU − Variable Cost Per Customer). You can also calculate break-even in terms of number of subscribers needed. Factor in churn, as you need enough new subscribers each month to replace churned ones plus grow toward break-even.
